feat(code-server): add machine settings option (#88)

Should resolve #27

The goal is to provide a method for template owners to configure default
`Machine Settings` that can be overridden by developers via `User
Settings` and repositories via `Workspace Settings`.
This option allows template owners to push new settings options with a
template release that would not be ignored because the setting file
already exists.
This also formats the `settings.json` file if `jq` is installed.

Eventually, I would imagine the current `settings` option will be
depreciated in favor of this option.
